There was a large white dog, had the shape and height of a lab but could precisely say the breed, running loose on banwell road, towards little river. It was about 12:30am and the collars were on it. Tried to approach it but it ran. I called the humaine society and walker vet and they said they would leave messages for the morning crew and try to get someone out there to find it.
Truly hope you find you find your dog or this helps you.
